Issue

If you’re trying to connect to either Redshift or Postgres and running Pandas somewhere in your code, you might come across the following error:

Error loading shared library libstdc++.so.6: No such file or directory
(needed by /usr/lib/python3.6/site-packages/pandas/_libs/window.cpython
-36m-x86_64-linux-gnu.so)

Fix

This is a pandas-related compatibility issue akin to this. The solve is similar - add the following to your packages.txt:

libgcrypt=
libxslt-dev
g++
libstdc++

That should do the trick.

Thanks, I’ll try this now.

FYI I ran into this error in a new environment that has no code uploaded or packages.txt - I was testing a manually added database connection

I’ve edited packages.txt to match the above then run astro airflow deploy

I select my airflow deployment then get this error:

Hi @ollieglass! We ended up sorting this out via support, but for anyone else following - the error on astro airflow deploy posted above is caused by an incompatibility related to the libgcrypt package we added above.

As a fix, remove the tag from the package. In your packages.txt, replace libgcrypt=1.8.3-r0 with just libgcrypt- that’ll install the latest version of the package.
